Hi Lyle,
Yes, I have both varieties. I think the artist mistakenly copied the last digits of the number on the saddle to the show reservations number. Phone number differences are one of the things to look for in identifying varieties on hotel matches. Tropicana is another hotel that changed their phone numbers a lot; I don't think most of those were printer's errors, though, just changes in the assigned numbers.

This is another Rivera variety I like. Shows the change in the stylized Hotel name, both inside and outside the cover.
